You are playing handpuppet of the jackass, actually. Check PATH_MAX in the Linux Kernel. J On Wed, 15 Aug 2007 12:53:18 -0400 monikerd <monikerd () gmail com> wrote:

Or perhaps your local privilege escalation scenario? JI'll play advocate of the devil then. Imagine a wiki running on a webserver, that allows anybody to create new topics which end up in /articles/[Topic].txt with sufficient .htaccess stuff in /articles to twart most usual attacks .. If you could create an arbitrary long topic, then you *might* be able to execute some code, when some cronjob would scan the drive and come across the file? creating files is a different privilege than running code. Hence imho it's not a bogus advisory. another possibility would be to create an archive that extracts an incredibly long filename perhaps? scanning an archive before/after it's extracted is a pretty common event i guess.
